Pixel Streaming - Embed Virtual Art Gallery on Client's Website

I produce Virtual Art Galleries for clients using Ue4 to build the demos - le Roux Gallery. - YouTube

I have clients who want this application embedded on their website so users can log on and interact with the gallery, walk around etc. At the moment I can only embed videos like the example above.

I’ve looked into Pixel Streaming and using companies like Furioos to embed my demos online, but the results were still a bit laggy.

Does anyone know any better workflow?

Amazon AWS Cloud?

Hosting users with a dedicated Server ( That sounds expensive setup and running costs)

Using companies like Furioos.

Any suggestions as to be able to give clients the option to embed playable demos on their websites?

Thanks.
